Specification of Letters Patent; Patented J 311; 23 1912 Application filed my 17,1911. Serial No. 627,868. 1 y y Fo all whom it may concern:

I Be it known that L'VVALTER E. S'UES$,C1JC17 zen of the United States. residing at Taylor, in the county of l/Villiamson andState of Texas, have invented certain new and useful Improvements in Stopocks, of which the following is a specification. 1

This invention relates to stop-cocks especially adapted to be used upon water service pipes and which is provided with a combination set of cores which mustbe operated in a peculiar manner before the passageway through the cock is opened. In other words the device is in the form of a key operable lock stop-cock, andthe parts mustflb eproperly manipulated at proper times in order to open thepassageway through the same.

For a full understanding of the invention reference isto be had to the following de; scription and accompanying drawings, in which: i

Figure 1 is a side elevation of. the stop cock; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a side elevation of a por tion of the cock, showing a portion of the key in section; Fig. 1 is-aperspective view of an end portion of the key. 1 Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The Cook consists of a body 1 having at its opposite sides hexagonal nuts 2 to which are connected the ends of water pipes 3,

The body 1 is provided with the usual" central conical bore 4, and at its upper end and partially surrounding said'bore is an incomplete annular flange 5. A hollow, core 6 is seated in the bore 4 and is held therein by means of a washer '7, and a niit 8 is screw threaded upon the lower endof the said core I and holds the washer against the lower end of the body 1. This core 6 is provided at opposite sides with openings 9 which at.

times are adapted to register with the openings in the body 1 and the nuts 2 thereof.

A core 10 is journaled in'thecore 6 and is provided with a transversely disposed open-' ing 11 adapted at times to register with the openings 9 in the core 6. The core 101s held in position in the core 6 by means {of a washer 11 and nut 12 screw threaded upon the lower end of the said core 10 and holding the washer against the lower end of the core 6.

15 'carriedby the core 6; The key is further The core 10- is provided at its upperlend p with a head 13 which in turn is provided upon one side with afyertically disposed upper end with a lug 15 which. lies-between the ends of the arcua'te flange 5 and is adapted when/the core 6 is: turned to come in contact with the ends ofthe saidcflange,

whereby {the turning movement. of the said core is limited. A flat spring 161s securedat one end to the top of, the body 1 between the ends: of the arcuate flange "5 thereof and I nearer one end of the said flange thanjthe groove 14. The rcore [6 is provided at its a other. The free end-portion of thisspring projects up into the path of moyementot.

the-lug 15 andholds the lug againstturm ing' movement, to any considerable extent 7 6 until it is depressed. down below the path offmovenient of the lug. e The-key for operating the cock consists;

of a 17 having at itslower end a hollow I head 18. This head is provided upon itsi' inner side'with a spline l9. which is, adapted to enter the groove 141; provided in'- the head 13 of the 'core 10. The said head 18' is also provided at its edge'with spaced lugs .20" which are adapted toen ter the space .be-'

tween the ends of the flange 5 and lie at" opposite sides of the lug 15. "One of the lugs 26 is adapted to bear down against the free end .of the. spring 16 a'nd depress the same belowthe path of movement of the lug 15.

In operation, thekey 17 is applied to-the upper end of the core 10 so that the spline] 19 slips longitudinally within the groove 14:

of the head :13 thereof. This core lO'i's'then given .a quarter turn'which'brings its'opening 11 into register with the openings 9 in the core 6. When this happens the lugs 20 are above but at the opposite sides 'of the lug depressed so that the lugs 20 are moved down along the opposite sides'of'thelu'g .15 and one of the lugs 20 depresses the spring 16. Therefore there is noobstruction in thepath of movement of thelu g 15, and the said lug together with the core 6 may be rotated until the openings 9 are brought into ice 4 register with the openings through the ends of the body- 1, and thus a passageway is opened through the said opening through which water may'pass. When the water is shut off, the operation above described is reversed.v Therefore it will be seen that unless one is familiar with the manipulation of v11) the cook, it is impossible to open the same to cause a waste or to purloin the water, and even so it would be necessary to have a key to effect the proper relative movements of the parts. i

Having thus described the invention, what is claimed as new is:

1. A stop-cock comprising a body having at its opposite sides openings, a hollow core journaled in the body and having at its opposite sides openings, said core beingprovided at its upper end with a lug which extends over the top of the body, the body being provided at its upper end with an incomplete annular flange in the space between the ends of which the said lug is received, a spring secured to the body in the space between the ends of the flange and having a free end portion elevated into the path of movement of the said lug, a core journaled in the first mentioned core and having an opening adapted to register with the openings in the first mentioned core, and means for bringing the opening in the second mentioned core into register with the openings inthe first mentioned core, said means also being adapted to depress the spring out of the path of movement ofthe lug and engage the same, whereby the said cores may be turned in unison.

2. A stop-cock comprising a body having openings at its opposite sides, said body having at its upper end an interrupted annular flange, a spring attached to the body in the space between the ends of the fiange and having an elevated free end portion, a

core journaled in the body and having openings at its opposite sides, said core being provided at its upper end with a lug which lies in the space between the ends of said flange, the free end of said spring projecting into the path of movement of the said lug, asecond core journaled in the first mentioned core and having an opening adapted to register with the openings in the first mentioned core, a head provided upon the second mentioned core, said head having a vertically disposed slot, and a key carrying a spline adapted to enter the slot of the said head, said key having eccentrically positioned lugs which are adapted to receive between them the first mentioned lug, one of the last mentioned lugs being adapted to depress the spring below the path of movement of the first mentioned lug.

3. A stop-cock comprising a body having at its opposite sides openings, said body being provided. at its upper end with an incomplete annular fiange, a spring mounted upon the body between the ends of the flange and having a free end portion elevated and depressed toward one end of the flange, a hollow core journaled in the body and having openings at its opposite sides adapted to register with the openings in the body, said core having at its upper end a lug which lies in the space between the ends of the flange and into the path of movement of which the said spring normally projects, a second'core journaled in the first mentioned core and having an opening adapted to register with the openings in the first mentioned core, said second mentioned core having at its upper end a head provided with a vertically disposed groove, and a key having a central hollow adapted to receive the said head and provided with a spline adapted to enter the groove in the said head, said key having eccentrically positioned spaced lugs-adapted to receive between them the lug upon the first mentioned core and adapted to depress the spring below the path of movement of the first mentioned core, whereby the said cores may be turned in unison.

In testimony whereof, I afiix my signature in presence of two witnesses.
